Review Summary
Your implementation correctly creates the notification structure with proper elements and timing logic, but there's a critical requirement violation: you're using opacity: '0' to hide notifications instead of the required display or visibility properties. The task explicitly requires using style attributes to hide messages, not opacity transitions. With opacity: '0', the element remains in the DOM flow and still occupies space, which doesn't properly hide it. Please change the hiding logic to use div.style.display = 'none' or div.style.visibility = 'hidden' instead. This is the only blocker in an otherwise correct implementation.

The code sets opacity: '0' which only makes the element invisible but doesn't hide it from the document flow. Per the requirements, you must use display: 'none' or visibility: 'hidden' to properly hide the notification element.

Review Summary
Your implementation meets all requirements. The pushNotification function correctly creates notification elements with the proper structure (div with 'notification' class and type class, h2 with 'title' class, and p for description), positions them using style attributes, and hides them after 2 seconds using setTimeout with display: 'none'. All three notification types (success, error, warning) are properly implemented and called. The previous issue with opacity has been correctly resolved to use display: 'none' as specified. Great work!
